Original posting: http://lkml.kernel.org/r/20121214184202.F54094D9@kernel.stglabs.ibm.com Several architectures have similar stack debugging config options. They all pretty much do the same thing, some with slightly differing help text. This patch changes the architectures to instead enable a Kconfig boolean, and then use that boolean in the generic Kconfig.debug to present the actual menu option. This removes a bunch of duplication and adds consistency across arches. Signed-off-by: Dave Hansen <dave@linux.vnet.ibm.com> Reviewed-by: H.

Unmap pages from the kernel linear mapping after free_pages().

This results in a large slowdown, but helps to find certain types
|
|
of memory corruptions.

If you say Y here the resulting kernel image will be slightly larger
|
|
and slower, but it will give very useful debugging information.
|
|
If you don't debug the kernel, you can say N, but we may not be able
|
|
to solve problems without frame pointers.
